LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Jan. 6, 1914.

To all whom it may concern Be it known that we, SIDWELL M. ENGLISH andLAGRANGE V. EDMONDSON, citizens of the United States, residing atRenovo, in the county of Clinton and State of Pennsyl- Vania, haveinvented certain new and useful Improvements in Liquid-Fuel Burners, ofwhich the following is a specification.

Our invention relates to improvements in liquid fuel burners, the objectof the invention being to provide an improved construction which insuresthe even distribution of liquid fuel throughout an extended surface, andcompels the liquid fuel to move over the end of an inclined platform ina thin layer, extended throughout the width of the platform or in aplurality of relatively small streams and commingle with air forcedunder the lower end of said platform, and thoroughly intermix with theair to form a good burning mixture.

A further object is to provide in a burner of the character stated, aliquid fuel distributing platform which is inclined from one end to theother, and on its upper face is formed with a plurality of longitudinalgrooves which communicate at their upper ends with a relatively largetransverse passage having at the center thereof, aconical distributerwhereby the liquid fuel is caused to uniformly enter the several groovesand discharge uniformly at the lower ends of said grooves, so that thefuel is equally distributed throughout the entire width of the latformand insures a proper commingling of the fuel and the air, so'that a richuniform mixture is had, the proportion being cont-rolled by the feed ofliquid fuel.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a view in side elevationillustrating our improvements. Fig. 2 is a view in longitudinal verticalsection. Fig. 3 is a view in section on the line 3-3 of Fig. 2. Fig. 4:is a view in section on the line 4-4 of Fig. 2, and Fig. 5 is afragmentary view in transverse section ,on 'an enlarged scale on theline 55 of Fig. 3.

Our improved burner comprises a single integral casting consisting of anouter casing 1 of general rectangular form which at its inlet end mergesinto an air chamber 2 in the form of an elbow. A relatively large pipe 3communicates with the lower end of the elbow, and is adapted to beconnected to any suitable fan blast apparatus. A relatively small pipe 4communicates with an opening 5 in the rear end of the elbow in line withthe center of casing 1. This pipe 4 is adapted to be connected to anysuitable compressor or source of supply for compressed air, so that airmay be forced through the casing. It is, of course, to be understoodthat these different sources of air are to be used separately and nottogether in accordance with the facilities at hand.

In the casing 1, our improved inclined liquid fuel distributing platform6 is located. This platform 6 is integral with the casing, extends fromside to side thereof, merges into the top of the casing at the upper endof the platform, and at its lower end terminates above the bottom of thecasing and short of the discharge end of the casing as clearly shown inFig. 2. This platform 6, on its upper face, is provided with a series ofparallel grooves 7, the series extending throughout the entire width ofthe platform and adapted to convey the liquid fuel to the lower end ofthe platform over which it falls and commingles with the air passingunder the lower end of the platform and burns at the point of juncture.

Near the upper end of platform 6 and on its upper face, an integraldistributer 8 is pro vided, and this distributer is of general conicalform, although it is not a true cone, yet all of its sides taper to apoint at the top of the distributer, and this pointed end is in linewith the center of a liquid fuel inlet 9 in the top of casing 1, and towhich fuel is fed by a pipe 10 connected to any suitable source ofsupply.

The upper face of platform 6 at its upper end is formed with atransverse passage 11 into which the rear half of the distributer 8extends, and at its ends said groove curves slightly downward, anddischarges directly into the outer groove 7. By reference particularlyto Fig. 5, it will be seen that all of the grooves, with the exceptionof the two central grooves, communicate with this passage 11, but at theentrance ends of said grooves 7 their bottoms are in a slightly higherplane than the bottom of passage 11. This difference in elevation isgraduated, so

that the grooves nearest the center have their bottoms higher thantheothers from the intermediate portions toward the sides of the platform.This is designedly true such, liquid, fuel will be flowing down thevseveralgroovesat an even depth, so that it is equally distributedthroughout the entire surface of theplatform.

As above statechthe distributer Sis not a.

true cone, but is somewhat flattened on its upper side, so that theliquid fuel will pass in greater proportion. intothe passage 11, thanintothecentral, grooves 7, so that by this means a better distributionof the liquid fuel is had. Thisequal distribution is carried out. evenwith the small-est quantity which can be fed, becausethe pointed;conical. distributer: compels the liquid to divide and run down thesides thereof into the several grooves, when. it falls from the inlet 9.

Various slight. changes might bemade in the general! form andarrangementof parts described: without departing from, our invention,and hence we do notlimit ourselves to the precise details set forth, butconsider ourselves at liberty to make such changes and alterations asfairly fall within the spirit andscope of the appendedclaims.

Having thus described our invention,

what, we claim as new and desire to secure by Letters Patent is:

1. Aliquidfuel burner comprising a casing havingla fuel inletin its top,an inclined liq uid fuel distributing platform in the casing,

said platform having a series of longitudinal;

grooves in its upper face, and a: tapering distributor in line with thefuel inlet to said casing, said distributer located at. the upper end ofthe platform, and adapted to compel the liquid fuel to. divide and passuniformly down the several grooves of the plat-form, substantially asdescribed.

2. A liquid fuel burner comprising a casing havinga fuelinlet in itstop,.an inclined liquid fuel distributing platform in the casing,

terminating at its lowerend above the bot tom of, the casing, means fordirecting air through said casing and under the lower ndof said.platform, said p at ormhaving.

a series oflongitudinal liquid fuel carrying grooveson. its outer face,an inclined distrlbuter having a pointed upper end in line .withtheinlet in the top of the casing whereby the liquid fuel falling upon thedistributer WillbG- -OOIIIPGllGCl to pass uniformly said passage at itsends communicating with the end grooves of the platform, and between itsends communicating with; the ends of the intermediate grooves, thelatter located. at different elevations with relation to the bottomofthepassage in regular ratio.

from the outer tothe inner grooves, and an inclined distributer locatedcentrally, with relation to the passageand. the grooves and in line withthe fuel inlet in the top of said casing, substantially as describeds4c. Aliquid fuel. burner consisting of an in tegralcasting'comprising arectangular hor-i zontal portion having an-integral-elbow at one end,an'air b-lastpipe communicating with the lower end of said elbow, acompressed air supply pipe communicating with the rear wall of theelbow, aninclined integral plat form in the casing extending from sideto side thereof, and .at its upper end merging into the top wallof. thecasing, said platform at its lowier end terminating short ofthe upperend of the platform, and a conical distributer integral with theplatformand' located in line with said fuel inlet, substantially asdescribed,

In testimony whereof We havesigned our names to this specification inthe presence of two subscribing witnesses.
